To create a Postprocess parameter that can be controlled by a blue print:

1. First create a Post Process Material. In that Material have whatever parameters you would like to control from Blue print.
   

   

2. Now create a Postprocess component in your blueprint

3. Create an instance of the Post process material during beginplay or wherever in your blueprint.

4. Make that instance into a post process setting using MakePostProcessSettings and MakeWeightedBlendables. This should apply your Postprocess Material to your PostProcessVolume
   

   

5. Now use your BP to call the material parameters and do the changes you want to.
